Description
Technical Field
The invention belongs to the technical field of agricultural planting, and particularly relates to a method for quickly propagating lotus in more than one year.
Background
The lotus is a perennial aquatic herbaceous plant, has beautiful flower and leaf, rich flower color, long flowering period and extremely high ornamental value; the roots of the lotus can absorb toxic substances such as lead, mercury, phenol and the like in water, and are rare water body purification plants; in addition, the lotus also has medicinal value.
At present, lotus planting mainly adopts lotus root introduction and seed introduction.
Seed introduction: the transportation is convenient, the introduction can be carried out all the year round, but the lotus variety belongs to multi-generation hybrid plants, the seeds are all hybrid seeds, and the characters of female parent (fruiting variety) are not maintained.
Lotus root seeding: the lotus variety is bred and maintained by the lotus root, the transportation is convenient, the long-distance transportation can be realized, and the variety characters can be ensured. However, the lotus roots are brittle, and the lotus roots are easy to break during transportation, so that survival is affected. Moreover, the lotus roots are different in size, so that the lotus roots are sold, the selling time is short, only two, three, four and three months can be sold in each year, and the lotus roots are not beneficial to popularization of ornamental lotus flowers.
Therefore, the existing method for breeding the lotus still has a plurality of defects, so that the lotus variety is difficult to introduce for planting and popularization in the growing season of the lotus.
Disclosure of Invention
The invention provides a method for quickly propagating lotuses for more than one year, which is beneficial to propagation and popularization of the lotuses.
The technical scheme of the invention is as follows: a method for rapidly propagating lotus in multiple stubbles in one year comprises the following steps:
(1) carrying out germination acceleration on the planted lotus roots;
(2) when the lotus roots grow floating leaves, carrying out separate planting, and separating main buds and old lotus roots;
(3) after each separate planting, when the main bud grows into a plurality of mature leaves, carrying out separate planting again, and separating the first mature leaf with the side bud and the root system at the tail part from the plant together to obtain plant tissues;
(4) circularly operating the step (3), and separately planting and taking seedlings four to five times in the growing season;
(5) and (3) additionally planting or cultivating the plant tissues subjected to the separate planting in a small container, uniformly managing and promoting the lateral buds to develop into new complete plant larvae, and selling or separately planting and propagating the plantlets after the seedlings are revived.
According to the method, after the floating leaves of the lotus roots grow, the main buds are separated, after the main buds grow mature leaves, the main buds are subjected to separate planting and separation again, and repeated circulation operation is carried out, so that a large number of new plants can be obtained, the method is convenient in material obtaining, and a large number of plants can be obtained.
In addition, the plants can enter dormancy to be incapable of continuously growing when reaching a certain density in the lotus plant process, and the planting density of the plants can be reduced and the lotus dormancy is avoided by the separate planting mode, so that the reproduction speed of the lotus can be increased.
The time selection of the separate cultivation is very important, the separate cultivation is carried out only after the lotus roots grow a plurality of floating leaves, and preferably, the separate cultivation is carried out when the lotus roots grow more than three floating leaves in the step (2).
Preferably, when the main bud separated in the step (2) is separated, two complete mature leaves are ensured. When the main buds ensure two complete mature leaves, the main buds can keep the growth fertility and are more favorable for the propagation and growth of the main buds after the separate planting.
In the invention, after the separated main bud is planted and a plurality of mature leaves are grown, the main bud is again separately planted, preferably, in the step (3), when three mature leaves are grown from the main bud, the main bud is again separately planted.
Preferably, in the step (5), the seedlings are released for two weeks and then sold or separately cultured.
Preferably, in the step (1), the lotus roots are planted before and after the Qingming festival to accelerate germination.
Preferably, in the step (1), the film is covered when the lotus roots are planted. The covering film can accelerate the germination and leaf growth of the lotus roots.
Preferably, in the step (3), after the main bud grows into a mature leaf, after drought stress treatment, the main bud is subjected to secondary transplanting, and the first mature leaf at the tail part is separated from the plant with the lateral bud and the root system together to obtain the plant tissue. The drought stress treatment is carried out, the growth environment of the plants is changed under the stress of the drought environment, the biomass of the plants is obviously changed, the water and nutrition supply of leaves is insufficient, the biomass of the plants is gathered to the lower part (roots and underground stems), the number and the length of functional roots are obviously increased, and the growth of the underground stems (lotus roots) is promoted, so that the growth of plant tissues can be enhanced by carrying out the separate planting after the drought treatment.
Preferably, when drought stress treatment is carried out, water in the planting area is removed, and after soil is cracked, secondary planting is carried out. During the separate planting, the drought treatment is carried out, when soil cracks slightly, the dry cracking phenomenon occurs, then the separate planting is carried out, the treatment mode reduces the moisture in the soil, and the growing environment is changed through adversity.
Preferably, the water content in the soil is kept between 80 and 90 percent during drought stress.
Compared with the prior art, the invention has the beneficial effects that:
(1) the characteristic of strong growth capacity of the lotus is utilized, continuous separate planting can be carried out in the growing season, the materials are convenient to obtain, and a large number of new plants can be harvested.
(2) The method can avoid intensive propagation of the lotus plants, further avoid dormancy of the lotus, greatly improve the propagation speed of the lotus, provide propagation material support for popularization and application of the lotus in growing seasons, reduce the purchase and investment cost of the propagation material, and facilitate application and popularization in landscaping.
(3) When the lotus is propagated, a large amount of land resources are not occupied for propagation, and a large amount of manual operation is not needed, so that the input cost of the land resources and the labor resources is greatly reduced.
(4) When the method is used for separate planting, the growth environment is changed through drought stress, so that the number and the length of functional roots are obviously increased, the growth of underground stems (lotus roots) is promoted, and the growth capacity of plant tissues is enhanced.
